The effects of Lactobacillus buchneri with or without a homolactic bacterium on the fermentation and aerobic stability of corn silages made at different locations
Open accessAbstract
Whole-plant corn (31 to 39% dry matter) from several locations was chopped, treated with nothing (U), Lactobacillus buchneri 40788 (4 x 10(5) cfu/g; LB), or L. buchneri (4 x 10(5) cfu/g) and Pediococcus pentosaceus (1 x 10(5) cfu/g; LBPP), and packed into quadruplicate 20-L silos to determine their effects on silage fermentation and aerobic stability after 120 d of storage. The experiment was a randomized complete block design with main effects of treatment (T), block (location; L), and T x L interaction. Dry matter recovery was different among locations but unaffected by T. The population of lactic acid bacteria was greater in LB and LBPP than in U, and the opposite was true regarding the population of yeasts. Numbers of L. buchneri (colony-forming unit equivalents), determined by a real-time quantitative polymerase chain reaction, were higher in 4 of 5 locations for LB and LBPP compared with U (T x L interaction) with an average 6.70 log cfu/g for LB and LBPP versus 4.87 log cfu/g for U. Silages inoculated with LB and LBPP had higher silage pH and higher concentrations of acetic acid and 1,2 propanediol but lower concentrations of ethanol and water-soluble carbohydrates; there was a T x L interaction for all these variables. Aerobic stability was improved by LB and LBPP (mean of 136 h) compared with U (44 h), but there was an interaction between T x L. In general, locations with the highest population of L. buchneri had the largest increases in acetic acid and, consequently, the greatest improvements in aerobic stability. The addition of L. buchneri 40788 alone or with P. pentosaceus resulted in similar effects on silage fermentation and aerobic stability, but the effects were variable among locations, suggesting that unidentified factors; for example, in the field or on the forage crop, may alter the effectiveness of microbial inoculation.

Aerobic deterioration involves, to different extents, up to 20% of the total stored DM of farm silages, both in temperate and warm climates.
“This deterioration process involves, to different extents, up to 20% of the total stored DM of farm silages, both in temperate (Vissers et al., 2007; Borreani and Tabacco, 2010; Schmidt and Kung, 2010) and warm climates (Huisden et al., 2009; Kang et al.,”
From Silage review: Factors affecting dry matter and quality losses in silages (2018) · cites this paper as Schmidt and Kung, 2010
The Introduction states that aerobic spoilage causes nutrient and dry-matter losses and that corn and small-grain silages are sensitive to it. It does not substantiate losses of up to 20% of total stored dry matter in farm silages; the paper instead tests corn silage in experimental silos. No page numbers were available in our copy.

Experimental — accuracy not yet measuredThe most common pairing in the literature has been with Pediococcus pentosaceus.
“The most common pairing in the literature has been with Pediococcus pentosaceus”
From Silage review: Recent advances and future uses of silage additives (2018) · cites this paper as Schmidt and Kung, 2010
The Introduction describes an earlier study pairing L. buchneri with P. pentosaceus, and the present study tests the same combination. Neither the Introduction nor the Discussion compares how frequently different pairings appear in the literature, so the claim that this pairing is the most common is not supported. (LLM, conf=0.85)
Experimental — accuracy not yet measuredIn Control, rapid lactic acid accumulation increased the LA/(AA + EtOH) ratio up to 2.67 after 32 days, significantly different (p < 0.001) from inoculated samples (1.05 to 1.58), but in line with published results for homofermentative populations.
“In the Control samples, as mentioned earlier, rapid accumulation of lactic acid was observed, triggering an increase in the LA/(AA + EtOH) ratio, up to 2.67 after 32 days, which differed significantly (p < 0.001) from the ratios calculated for the inoculated samples, between 1.05 to 1.58, but were in line with published results [65] for homofermentative populations at that period [66] (Table 1).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
